After extensive testing we found the imaging drums will normally run up to 2 more cycles after the initial cycle before the print quality requires a new drum. To reset a drum unit you simply stick the chip onto the drum unit.

It takes less than 2 minutes to reset an imaging drum. There are no tools required. The clear instructions below demonstrate how easy this is to do and it's actually quicker and less messy than replacing a drum. This can be easily done in an office environment.
